In the past course has been recorded with a pen-plotter and highly expensive custom graph paper. The KW991 uses a low cost dot matrix printer and plain paper (roll or fan-fold), and it prints intelligently in plain text, along with time.

 

The data may be recorded on a PC using a free data logging program, as a simple Voyage Data Recorder.

 

GPS input provides timing. A routine log of position and speed over ground is printed. The output data rate is variable, automatically, to this simple rule, to minimize the use of paper.

 

Product Description

•Printout on low cost printer
•Digital heading repeater
•Low cost replacement for “course recorders.”
•Connects to a gyro and a GPS.
•Highly reliable, 1000s in service.

 

The KW950-E is programmed to output a single line of data at certain intervals. The data is printed on a tandard low cost printer, or to a PC for recording on disk. The interval between outputs varies according to these rules, in order to
minimise paper used, and to provide a good record of data.

 

a) One line output every 6 minutes on a 6 minute interval. (0, 6, 12 etc. 1/10th hour.) Paper usage on passage would be typically 4 pages per day.
b) An output if course changes by 2 degrees from the last output. This occurs no faster than at a 10-second interval. Paper usage during manoeuvring would be typically 3 pages per hour.
c) An output on demand by pressing the keypad AL button.
